Extrusionseinrichtung
Beschreibung Extrusion device
Description

Die Erfindung betrifft eine Extrusionseinrichtung nach dem Oberbegriff des Anspruchs 1. Bekannte Extrusionseinrichtungen weisen mit Getrieben gekoppelte Einzugswalzen und Extruderschnecken auf, die von einem gemeinsamen Antriebsmotor angetrieben sind. Infolgedessen ist das Drehzahlverhältnis zwischen den Einzugswalzen und 0 den Extruderschnecken aufgrund der Getriebeübersetzungen vorgegeben. Daher kann der Befüllungsgrad eines Extruders, je nach dem gerade verarbeiteten Produkt unterschiedlich sein.The invention relates to an extrusion device according to the preamble of claim 1. Known extrusion devices have feed rollers and extruder screws coupled with gears, which are driven by a common drive motor. As a result, the speed ratio between the feed rollers and the extruder screws is predetermined by the gear ratios. The filling level of an extruder can therefore vary depending on the product being processed.

Aufgabe der Erfindung ist es daher, den Befüllungsgrad eines Extruders unabhängig vom Produkt optimieren zu können. Diese Aufgabe wird mit einer Extrusionseinrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch die getrennten Antriebe der Einzugswalzen und der 0 Extruderschnecken ist es möglich, deren Drehzahlen zur Erzielung eines optimalen Befüllungsgrades des Extruders aufeinander abzustimmen. Besonders vorteilhaft zur Reduzierung der erforderlichen Antriebsmomente der Einzugswalzen und der Extruderschnecken ist es, dieThe object of the invention is therefore to be able to optimize the filling level of an extruder independently of the product. This object is achieved with an extrusion device with the characterizing features of claim 1. Due to the separate drives of the feed rollers and the extruder screws, it is possible to coordinate their speeds to achieve an optimal filling level of the extruder. It is particularly advantageous to reduce the required drive torques of the feed rollers and the extruder screws to

R. 35859R.35859

Einzugswalzen und die Extruderschnecken jeweils mit einem Getriebe auszustatten.The feed rollers and the extruder screws are each equipped with a gear.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail below.

Die einzige Figur zeigt einen Teil eines Extruders in einer vereinfachten Seitenansicht.The only figure shows part of an extruder in a simplified side view.

Der in der Figur dargestellte Teil eines Extruders 10 zeigt einen ersten Getriebekasten 11 mit einem 2-stufigen Getriebe, das wenigstens eine Extruderschnecke antreibt. An den ersten Getriebekasten 11 ist ein erster Antriebsmotor für die wenigstens eine Extruderschnecke angeflanscht. Mit dem ersten Getriebekasten 11 ist ein zweiter Getriebekasten 13 ausgerichtet, der ein 4-stufiges Getriebe für wenigstens eine Einzugswalze trägt. An den zweiten Getriebekasten 13 ist ein zweiter Antriebsmotor 14 für die wenigstens eine Einzugswalze angeflanscht. Die Antriebsmotoren 12, 14 sind 0 mit der Steuereinrichtung des Extruders 10 verbunden und von dort aus in ihren Drehzahlen getrennt regel- bzw. steuerbar. Dadurch wird es ermöglicht, die Drehzahlen der wenigstens einen Einzugswalze und der wenigstens einen Extruderschnecke derart aufeinander abzustimmen, daß ein optimaler Befüllungsgrad des Pressengehäuses des Extruders 10 erzielt werden kann.The part of an extruder 10 shown in the figure shows a first gear box 11 with a 2-stage gear that drives at least one extruder screw. A first drive motor for the at least one extruder screw is flanged to the first gear box 11. A second gear box 13, which carries a 4-stage gear for at least one feed roller, is aligned with the first gear box 11. A second drive motor 14 for the at least one feed roller is flanged to the second gear box 13. The drive motors 12, 14 are connected to the control device of the extruder 10 and their speeds can be regulated or controlled separately from there. This makes it possible to coordinate the speeds of the at least one feed roller and the at least one extruder screw in such a way that an optimal filling level of the press housing of the extruder 10 can be achieved.
